Dr. Payal Kohli has shared clinical insights into a new oral immunotherapy approach that could help millions of Americans manage dairy allergies by desensitizing the immune system to milk proteins. According to reports from 9NEWS, the treatment protocol exposes patients to gradually increasing amounts of an allergen under medical supervision, shifting how the body reacts to accidental ingestions.
Understanding Dairy Allergy Mechanics
A true food allergy to milk involves the immune system mistakenly identifying specific proteins—primarily casein and whey—as harmful invaders. According to the American College of Allergy, Asthma and Immunology, this triggers the production of Immunoglobulin E (IgE) antibodies, leading to histamine release and symptoms ranging from hives and vomiting to life-threatening anaphylaxis. Traditional management relies strictly on avoidance and carrying epinephrine, which leaves patients vulnerable to cross-contamination risks in everyday foods.
Oral immunotherapy changes this dynamic by retraining immune cells. Dr. Payal Kohli explained in the 9NEWS coverage that small, controlled doses of dairy are introduced to the patient over weeks and months. This process aims to raise the threshold of what the body can tolerate, reducing the severity of reactions if accidental exposure occurs.
Clinical Protocols and Safety Measures
Desensitization therapy requires strict oversight from board-certified allergists in clinical settings equipped to handle acute allergic reactions. Patients begin with micro-doses of dairy protein, often measured in milligrams, at the doctor’s office. Doses increase incrementally on a predetermined schedule until the patient reaches a designated maintenance amount.
Medical guidelines emphasize that oral immunotherapy is not a cure. Patients who successfully complete the protocol typically must continue consuming the allergen daily to maintain their desensitization. Stopping regular consumption can cause the immune system to revert to a reactive state.
Patient Impact and Outlook
For families managing severe milk allergies, therapies that reduce the constant anxiety of accidental exposure offer a significant shift in daily life. Dr. Kohli noted that while the treatment involves rigorous adherence and carries a risk of side effects like gastrointestinal discomfort or allergic symptoms during dose increases, it provides a viable pathway for patients to integrate dairy safely into their diets over time.
